Upper internal butts of brackets are interjoined by means of longitudinal beam. EFFECT: prolonged service life of electrolyzers. 1 dwg

Description

 The proposal relates to the field of metallurgy and can be used in building structures of the electrolysis housing.

 A support device is known for the carriageway of the aluminum electrolysis body (see A. KOSTIUKOV et al. Non-ferrous metals metallurgy reference book. Aluminum production. Moscow, Metallurgy, 1971, p. 313, Fig. 160).

 It is made in the form of external and internal supports for corrugated floor slabs. At the same time, the walls of the supply channels (in single-storey buildings) or bus channels (in two-storey) are used as external supports, and the longitudinal walls of the cathode casing are used as internal channels.

 A disadvantage of the known device is the following. Processing the baths with mechanisms for punching the crust of the electrolyte and the movement of vehicles along the corrugated slabs negatively affect the integrity of the cathode part of the electrolyzer, because one of the supports of the corrugated supports of the floor slabs are the longitudinal walls of the cathode casing.

 The objective of this proposal is to increase the technical and economic results of the aluminum electrolyzer.

 The technical result of this proposal is to increase the life of the cell.

 The technical result is achieved by the fact that in the device containing the internal and external supports and floor slabs, the internal supports are made in the form of L-shaped brackets, supported by the lower end on the electrolyzer base, and the upper external - on the external supports, while the upper inner ends of the brackets are connected between each other with a longitudinal beam.

 The essence of the proposal is as follows. To prevent the transmission of vibration from the operation of vehicles and mechanisms for punching the electrolyte crust, instead of laying one of the edges of the corrugated floor slabs on the side of the bath, it is proposed to lay these plates on the L-shaped brackets.

 The support for these brackets is, on the one hand, the support (foundation) of the cathode part of the electrolyzer, and on the other hand, as in the prototype, supply or bus channels.

 Common features of this proposal and the prototype are the following features. The presence of internal and external supports for corrugated floor slabs.

 The difference lies in the fact that, as internal supports, supports under the electrolyzer are used with the help of L-shaped brackets, the lower end is installed on the supports under the electrolyzer, the upper external to the external supports, and the upper internal ends are connected by a longitudinal beam. This embodiment, in contrast to the solution of the prototype, eliminates the possibility of transmitting vibration from the operation of vehicles directly to the walls of the cathode device and thereby helps to maintain its integrity, and ultimately increase the life of the cell.

 Given the above, we can conclude that this proposal meets the criteria of the invention of "novelty."

 To compare offers with other well-known solutions, a search was carried out in patent and scientific and technical literature.

 No technical solutions similar to the proposed were found. Therefore, we can conclude that this proposal meets the current level of technology.

 The proposal is illustrated in the drawing, which shows a General view of the device.

 The device contains L-shaped brackets 1, the lower end 2 of which is mounted on the internal support 3 (the base of the cell 4). The upper external end 5 of the bracket 1 is installed on the external support 6 - supply (or bus) channel. The upper inner ends of the brackets 1 are interconnected by a longitudinal beam 7. On these beams, brackets 1 and support 6, corrugated floor slabs 8 are laid that form the floor of the roadway of the electrolysis workshop.

 The device operates as follows.

 The bath 9 of the electrolyzer 4 is periodically treated with mechanisms for punching the crust of the electrolyte. In addition, operations are performed on filling alumina, pouring metal, etc. From the operation of these mechanisms and vehicles, shock, vibration, etc. loads arise, which are transferred directly to the foundation 3 through L-shaped brackets 1, bypassing the body of the bath 9.

 Thus, this proposal provides an increase in technical and economic indicators of the electrolyzer by increasing its service life by reducing the impact of shock, vibration and other loads on the body of the bath 9 of the electrolyzer 4.
